According to the kinetic theory, particles of different gases at the same temperature have the same
volume
pressure
molecular speed
average kinetic energy
Choose the INCORRECT statement.
Boyle 's Law states that the volume of the gas is directly proportional to its pressure
Kinetic theory of gases postulates that the volume of the gas particle is too small hence it can be ignored.
Larger value of a, in the van der Waals equation for a real gas, indicates a stronger attractive force between gas molecules.
